VAPOR-BURNER STOVE.

SPECIFICATION forming part of Letters Patent No. 327,647, dated October6, 1885,

Application filed February 14, 1885. Serial No. 155,952.

To all whom, it may concern:

Be it known that I, WILLIAM BLIESNER, of St. Louis, Missouri, have madea new and useful Improvement in Vapor-Burner Stoves, of which thefollowing is a full, clear, and exact description.

The improvement relates to the mechanism for operating the burner-valve.

The annexed drawings, making part of this specification, illustrate thatportion of a vapor-burner stove with which the improvement in questionis immediately connected and essential to an understanding thereof.

Figure 1 is a view in perspective of a burner having the improvement.Fig. 2 is a hori zontal section taken through the valve-stem andsupply-pipe above the level of the valve stem lever, and Fig. 8 is a topview showing a portion of the stove.

The same letters of reference denote the same parts.

A represents the stove. Saving as modified by the improved feature it isof the customary form.

13 represents the burner.

0 represents the stem of the bu rnervalve.

D represents a lever attached to the valvestem. The lever extends fromthe stern outward to or into the vicinity of the front a of the stove,substantially as shown in Fig. 3. The valve stem is operated by swingingthe outer end of the lever horizontally to the right and left-that is,to close the burner-valve the lever is swung in one direction, say tothe right, and to open the burner-valve the lever is swung in theopposite direction. The valvestem is adapted to move, and to close oropen the burner-valve according to the extent of the movement of thelever. To this end the valve-stern is threaded at c, and the threadedportion is adapted to work through a bearing, 0, so that as the lever isswung to and fro, as

described, the valve stem is raised and lowered in its bearing, and theperson using the stove can thus both readily operate the burner, andalso, from the position of the lever, determine whether the burner-valveis open or closed.

The lever is adapted to operate against a stop, so that it can bereadily determined when the valve is closed or opened. For this purposethe lever is extended at (Z and d, and in each extension is anadjustable projection say, in the form of the screw d \Vhen the lever isswung to the right, the point of the screw in the extension atencounters some fixed part of the stove-say, the supply-pipe E and whenthe lever is swung to the left the point of the screw in the extension dencounters the supply-pipe.

As the burner-valve is worn in use, or its seat enlarged, it isdesirable from time to time to swing the lever somewhat farther inclosing the valve. For this purpose the projection d is made adjustable,as stated, in the extension. By unscrewing the screw in the extensionthe lever can be moved through a greater are, and the burner-valveaccordingly moved. The screw in the other extension, d, can be similarlyadjusted to limit the throw of the lever in the opposite direction.

I elaim- 1. The combination of the valve-stem O, the stop E, the leverD, the extension (Z, and the adjustable projection (2 substantially asdescribed.

2. The combinaiion of the valvestem G, the stop E, and the lever D,having the extensions (1 d, and the screws (2 d substantially asdescribed.
